Abstract
An overlapping part of a first member and a second member is joined using a tool for friction stir spot welding and a rivet. The first member is disposed on a side where the tool is press-fitted first, and the second member is disposed on a side where the tool is press-fitted last, so that the overlapping part is formed. The tool is press-fitted into the overlapping part to perform friction stirring, thereby forming a friction stirred part in the overlapping part. The rivet is press-fitted into the friction stirred part from the first member side.
Claims25
A joining method using a tool for friction stir welding and a fastener to join an overlapping part formed including a first member on a tool side and a second member disposed below the first member, the joining method comprising:
- press-fitting the tool into the overlapping part to perform friction stirring, and forming a friction stirred part in the overlapping part;
- and
- press-fitting the fastener into the friction stirred part from a first member side.

A joined body of an overlapping part formed including a first member and a second member,
- the joined body comprising:
- an overlapping part in which the first member is disposed on one end side in an overlapping direction overlapping the second member disposed on another end side in the overlapping direction;
- a friction stirred part provided in the overlapping part;
- and
- a fastener press-fitted into the friction stirred part.

A joining device that joins an overlapping part formed including a first member and a second member, the joining device comprising:
- a pin member in a columnar shape that is movable forward and backward in an axial direction;
- a shoulder member in a cylindrical shape that is positioned covering an outer periphery of the pin member to be rotatable about an axis identical to the pin member and movable forward and backward in the axial direction;
- and
- a fastener that is loaded in an accommodation space created by raising of the pin member, and is press-fitted into a friction stirred part formed in the overlapping part by the pin member.
